Uses Kalman Filter technique in order to produce dynamic hedge-ratio for 2 highly correlated securities, which is then used to form a mean reversion trading model backtested over 22 years! WKFPR, unlike the raw price relative that measures only how much the price moves from one period to the next, measures how far the price deviates from the inherent trend value. %���� Many people have heard of Kalman filtering, but regard the topic as mysterious. A mean reversion strategy as above can then be applied to y. >> The presence of strong momentum and mean reversion in volatility processes provides a rationale for the kind of volatility strategy that we trade at Systematic Strategies. 17 0 obj I was trading these pairs intraday. 9 0 obj Would the hedge ratio change fast enough during real time trading to save me? Currently, there are 0 users and 1 guest visiting this topic. But there is no limit to perfection, so let us consider one more strategy and compare results. At the outset, we would like to clarify that this article on the Kalman filter tutorial is not about the derivation of the equations but trying to explain how the equations help us in estimating or predicting a value. For example, I have already described the use of low-pass filters. Thus, we propose a new approach for online portfolio selection, namely W-KACM, to capture the properties of mean reversion and momentum in stock prices. Below is the equity curve of the linear mean reversion strategy from the previous post on the three-instrument portfolio with the value of the portfolio overlaid on the equity curve: The strategy suffers significant drawdown and only returns a profit factor of 1.04 and a Sharpe ratio of 0.29.
